WHAT OUR CLIENTS SAY

We had Global Alarm install a system in our home we Air BNB from time to time. It works great! Easy to change the user codes notification of issues. Great to work with!

Wayne Lovejoy

Twenty three years ago I built a new home. The builder had a contract with ADT to install an alarm system. ADT installed the wiring and a control unit but then closed their offices here and left town. I called Global Alarm and told them I was in a bind. They said, no problem, we will be out tomorrow. They have handled everything that has ever happened for all this time. They are the best and fun to work with as well. I highly recommend them to take care of your security needs!

Terry Cooper

We’ve been customers for several years. The system appears to have been very reliable and on the couple of occasions when we accidentally set off the alarms, they were almost immediately responsive. I think we made a great choice of security providers.

Tim Gill

We have used Global Alarms for many years. The operators are quick to respond to alarms. The techs have always come out quickly to make any upgrades or repairs and are always courteous.

Joe and Kathy Birt

The folks at Global Alarm Systems are awesome and will treat you like family. When my office was burglarized on Christmas and again on New Year’s Day, these guys were there when I needed them most. They swiftly installed cameras, upgraded my security system, and caught the thief when he returned. Thank you Global!
